Summer Walker was heavily criticized for alleging that Covid-19 mRNA vaccines are contagious and can cause spontaneous abortions.

The R&B singer sparked controversy when she warned her followers that standing next to a vaccinated person can cause miscarriages and blood clots.

The 25-year-old singer made the unusual remarks in posts on social media on Monday.

"We're all f*****d," she wrote in her Instagram stories. "Stay the f*** away from people who were vaccinated. People are reporting bleeding, bruising, spontaneous periods and miscarriages from being in close [proximity] to a recently vaccinated person." She added the hashtag #YouHaveBeenWarned.

In a follow-up post Summer wrote in all caps:

"I'm alarmed by the amount of women in my DM's complaining about abnormal bleeding and miscarriages after coming in contact with someone whose been vaccinated!!!!!"

Instagram attached a Covid fact-checking information box to Summer's post noting that Covid-19 vaccines are tested for "safety and effectiveness".

Millions of people have reported adverse reactions to Covid-19 mRNA vaccines around the world. But there are no reports of contracting adverse effects from simply standing next to a vaccinated person.

More women are reporting side effects to the vaccine than men, according to a website that records side effects and deaths.

79% of women reported side effects in the first 13.7 million Covid-19 vaccine doses administered to Americans this year.

An infectious disease specialist says there may be a biological reason for the disparity in side effects to the vaccine.

"We know that with vaccinations and infections, women tend to have a stronger immune response than men," Dr. Simone Wildes, a Boston-based infectious disease specialist, told "Good Morning America." "That's really driven by biological differences in males and females and the sex hormones."

Wildes explained that men and women experience different side effects because the vaccines tells the body to make foreign proteins.

"When we get the Covid vaccine, we are introducing proteins into our body that are foreign and we're teaching the cells to make the antibodies and the T-cells to help to fight the infection in case we're exposed to it," she said. "What happens in the female body is those cells create more protein than the male cells would."

She added: "When females get the vaccine, we're going to complain of more side effects because our immune system is more revved up," Wildes explained. "We are able to produce more of the antibodies..."

Additionally, Wildes said women in general tend to complain more than men.

"Women in general just report more, so there is that difference," said Wildes. "I can’t tell you how many men I will see in the hospital who say, ‘My wife forced me to go to the hospital,' while some men will say, 'It's not a big deal.'"

So far, 38% of the U.S. population has been vaccinated. Only 14% of Black people have been vaccinated.

Covid-19 mRNA vaccines are causing an unexpected side effect in biological women. The still-experimental messenger ribonucleic acid (mRNA) vaccines have been administered to 65 million Americans.

Commonly reported side effects include pain around the injection site, headache, fatigue, muscle pain, and death.

But some women are complaining of an unexpected side effect after the second dose: swollen, painful mammary lymph glands that can mimic breast cancer.

"I panicked, I'll admit, initially," said Dr. Bridget Rogers, radiologist at Solis Mammography.

"I had a big, visible, painful lump," she told CBS4 Health Specialist Kathy Walsh. Dr. Rogers said she received her second dose of mRNA vaccine the day before.

"I tried to reassure myself by remembering that this is actually a sign that the vaccine was doing what it's supposed to do, activating your immune system," she said.

Still, she admits she had an ultrasound done just to make sure.

"I've been trying to forewarn women ahead of time," said Dr. Stephanie Miller, a breast surgeon and Medical Director of the Breast Program at Rose Medical Center.

She tells women to let the mammography center know if you've recently had a vaccine "So that we can have the right explanation for what we're seeing."

Mammary lymph glands are located in the arm pit and neck on the affected side.

Swollen, painful lumps in the armpit and in the neck under the jawline are among the first signs of breast cancer in some women.

Doctors urge women not to take the vaccine if you have a mammogram scheduled the next day because it may trigger a false breast cancer reading.

A former Detroit news anchor has died a day after receiving a Covid-19 mRNA vaccine. Karen Hudson-Samuels was found dead in her Detroit home by her husband, Cliff Samuels, CBS Detroit reported.

Hudson-Samuels, 68, worked at the country's first Black-owned television station. She also worked as a producer and news director at WGPR-TV.

"We suspect it may have just been a stroke but because of the normal side effects of the vaccine it may have masked that," Samuels told the news station.

"Hopefully we'll know soon from the autopsy report," he said.

"She was just a beautiful person," WWJ Reporter Vickie Thomas told WGPR. "It's such a huge loss for this community," Thomas said.

Over 1,200 Americans reportedly died within two weeks of receiving Covid-19 mRNA vaccines.

Drene Keyes, 58, died within hours of getting a vaccine at a Virginia facility on Feb. 6.

Keyes' daughter, Lisa Jones, told WKTR that her mother's job "made her eligible for the vaccine."

"Why are we allowing people with underlying conditions to be guinea pigs for a vaccine that is still in clinical trials and emergency use?"

A blood disorder that affects the platelets has been reported in at least 2 dozen people who received Covid-19 mRNA vaccines in the United States.

Thrombocytopenia is among the adverse effects reported to the Vaccine Adverse Event Reporting System (VAERS) system, which is jointly run by the U.S. Centers for Disease Control and Prevention and the U.S. Food and Drug Administration.

Thrombocytopenia is an abnormally low platelet count in the blood. A normal human platelet count ranges from 150,000 to 450,000 platelets per microliter of blood.

Low platelets causes abnormal bleeding, weakness and fatigue.

Signs and symptoms of low platelet count are frequent nosebleeds, bleeding gums, bruising all over the body, longer periods in women, small red or purple spots on the skin, spontaneous bleeding under skin, blood filled blisters inside the mouth.

MSN reports that by the end of January, 32 cases of a decreased platelet count, 14 cases of thrombocytopenia, and 11 cases of immune thrombocytopenia were recorded in people who had received either Pfizer or Moderna COVID vaccines in the U.S.

If you notice any unusual signs of bleeding after getting the mRNA vaccine, contact your doctor or healthcare provider immediately.

As the U.S. and other countries prepare to roll out millions of messenger Ribonucleic Acid (mRNA) vaccinations, UK officials warn the still experimental mRNA vaccinations will do nothing to stop the spread of the virus.

The U.S., Canada and the UK recently approved the vaccine developed by Pfizer and the German firm BioNTech for "emergency use."

But critics of the rollout say the mRNA vaccinations were not designed to stop the spread of a virus since, unlike traditional vaccines, the mRNA vaccines are bio-engineered to genetically modify human DNA.

In a letter sent Nov. 4 to the U.K.'s healthcare staff in four countries, chief medical officers say the vaccines will not stop the spread of the virus, and healthcare workers should prepare for "an specially hard winter."

"[Vaccine] deployment will have only a marginal impact in reducing numbers coming into the health service with COVID over the next three months," the officials wrote.

"Vaccines do not equal zero COVID," World Health Organization emergencies director Michael Ryan warned on Friday.

The vaccines pose a problem to healthcare workers because of the serious side effects reported by participants in clinical trials.

Buddy Creech, one of the lead investigators of the Moderna vaccine trials, said the side effects are strong enough to put health workers "out of commission" and those risks have to be raised before the vaccines are rolled out.

Officials at Massachusetts General Hospital and other hospitals in the U.S. are considering vaccinating doctors and nurses at the end of their shifts to stagger their staff in case they call out sick after receiving the shots.

But Mass General's vice chair of emergency preparedness Paul Biddinger says staggering shifts will not be enough since full data from Pfizer and Moderna's late-stage trials are still unknown.

The Food and Drug Administration (FDA) released a draft of possible side effects from the still experimental Covid-19 messenger RNA (mRNA) vaccine (link opens PDF).

The terrifying list looks like something out of a horror movie script. The scariest side effect (other than death) is disseminated intravascular coagulation (DIC).

In my 30+ years as a registered nurse I've only witnessed two patients suffering from DIC. Both patients died within hours.

DIC is the singular most horrific medical condition I've ever witnessed. Basically, DIC interrupts the body's normal clotting function and the patient bleeds from every orifice, including the eyes, nose and mouth.

Blood transfusions are pointless because of the lack of clotting factors. So the blood transfusions go into the veins and pour out through the nose, ears, eyes, vagina, anus -- even the pores in the skin ooze blood.

The following is a draft of possible adverse reactions to the mRNA vaccine.

A British pharmacy regulator has dropped a bombshell warning: people with significant allergic reactions should not take the still experimental Covid-19 vaccine.

The MHRA warned Wednesday that people who have experienced "powerful allergic overreactions" should avoid taking the experimental Pfizer/BioNTech mRNA vaccines.

The warning comes after 2 people reported adverse reactions after taking the Pfizer mRNA vaccines last week.

At least 2 volunteers in the Pfizer and Moderna trials have died after getting the vaccine in clinical trials in the U.S.

The adverse reactions spell trouble for the already risky vaccination program here in the U.S. where the elderly in nursing homes will be the first guinea pigs.

Dr. Sandra Fryhofer warned that patients will have some "rough side effects" from the vaccine that will last a day to a week. She said some healthcare workers who take the vaccine may have to call out sick the next day.

She is concerned that her patients will not return for the second dose if they are feeling poorly after the first dose.

"We really need to make patients aware that this is not going to be a walk in the park," Fryhofer said. "They are going to know they had a vaccine. They are probably not going to feel wonderful. But they've got to come back for that second dose."

One North Carolina woman who participated in the Moderna trials said, "The first dose is no big deal. And then the second dose will definitely put you down for the day for sure. You will need to take a day off after the second dose."

Researchers don't know the longterm effects of the mRNA vaccine, since the FDA has never approved mRNA vaccines for use in humans.

A Phase 3 vaccine developed by drug manufacturer AstraZeneca was put on hold when a volunteer in the UK fell ill after suffering a "serious adverse reaction" to the vaccine.

The vaccine being developed by drug manufacturer AstraZeneca and the University of Oxford in England was put on hold after a UK participant experienced a "serious adverse reaction".

The adverse reaction was described only as an "unexplained illness" in one of the trials.

A spokesperson for AstraZeneca, the frontrunner in the race for the first Covid-19 RNA vaccine, said in a statement on Tuesday that the company's "standard review process triggered a pause" to allow for a "review of safety data."

Another source within the company, who spoke to Statnews.com on condition of anonymity, said the adverse reaction is having an impact on other AstraZeneca vaccine trials, as well as clinical trials being conducted by different vaccine manufacturers.

Nine drug manufacturers have vaccine studies currently under way in the U.S. and abroad.

The U.S. is currently testing vaccines at 62 sites across the country, according to clinicaltrials.gov.

AstraZeneca's clinical trial is the first to reach the critical Phase 3 stage - the final step before the vaccine gets FDA approval. The normal timeframe for clinical trials is three years.

Adverse reactions to vaccines that require hospitalization may include life-threatening illness and even death.

Doctors in the U.S. are concerned that the vaccines are being rushed to market without adequate time to determine side effects.

Although healthcare professionals are due to get the vaccines first, many doctors and nurses say they will decline to take a vaccination that is rushed to market -- particularly since the Covid death rate is way below 1%.

Fully one third of Americans say they will refuse the vaccine if one is available before the election in November.

News of the adverse reaction sent AstraZeneca's stock tumbling 8% in after hours trading on Tuesday.
