A study published in Vaccine has shown that the COVID vaccine, which is given to women before they get pregnant, can cause a temporary change in the menstrual cycle of some women. While this study was small and only looked at a limited number of women, it’s still an important discovery that needs to be taken into account when making healthcare decisions for pregnant women.

What is COVID?

COVID is an abbreviation for the Centers for Disease Control and Prevention’s (CDC) Common Name for the virus that causes mumps, measles, rubella, and chickenpox. COVID is also the name of a vaccine developed to prevent these infections. So what is COVID?

COVID is a virus that can cause mumps, measles, rubella, and chickenpox. The vaccine created to prevent these infections is called COVID.

The Centers for Disease Control and Prevention (CDC) estimates that each year approximately 20 million people in the United States become infected with COVID. Of these people, about 1 million are hospitalize and 400 die from complications related to the virus.

What are the symptoms of COVID?

The symptoms of COVID can vary depending on which stage of the virus someone is infecte with. Early symptoms include fever, headache, muscle aches, and tiredness. Later symptoms may include swollen glands, diarrhea, and rash. Most people who contracted COVID experience only a few of these symptoms. However, some people develop serious illness such as meningitis or encephalitis (a brain inflammation).

What Are the Side Effects of COVID Vaccination?

There are a few potential side effects associate with COVID vaccination, but fortunately they are relatively minor and usually only last for a few days.

The most common side effect is a temporary change in the menstrual cycle. This can vary from a slight delay in the onset of menstruation to an absence of periods all together. For most women, this change resolves within a few weeks without any further complications.

Other side effects may include:

-A mild fever
-Muscle aches and stiffness
-Mild nausea or diarrhea
-Rarely, a allergic reaction which may include hives, rash, or difficulty breathing

How Common Are the Side Effects of COVID Vaccination?

There are a number of potential side effects associate with COVID vaccination. These side effects can vary from person to person, and can often be mild. However, some people may experience more serious side effects.

Some of the most common side effects of COVID vaccination include:

– Fever
– Rash
– Neck stiffness
– Swelling in the arms or legs
– Headache
– Diarrhea
– Rash on the face
– Itching
– Jaundice (a yellowing of the skin or eyes)
– Anaphylactic shock (a life-threatening allergic reaction)
*These are just some of the most common side effects. There are likely others that have not yet been identifie. If you experience any side effects after receiving a COVID vaccine, please talk to your doctor.

Can Temporary Change in Menstrual Cycle Be Causes by a COVID Vaccination?

There is a growing concern that the HPV vaccine, specifically the quadrivalent version, may be link to changes in women’s menstrual cycles. A study published in Vaccine in February 2018 found that girls who received the quadrivalent HPV vaccine before their 12th birthday experienced an increase in reports of amenorrhea (a drop in menstrual flow) and intermittent bleeding for at least six months after the vaccine. This was particularly prevalent among girls who reported changes in their cycles within three months of receiving the vaccine.

While these findings are still inconclusive, they add to the growing body of evidence that HPV vaccination can have unintended consequences. It is important to note that while amenorrhea and intermittent bleeding are both temporary changes. They can be very disruptive and lead to increased anxiety and stress levels for young women. If you or your childhas experienced a change in your menstrual cycle after receiving a HPV vaccine, it is important to speak with your doctor for further assessment.


We recently reported on the study linking the seasonal flu vaccine and an increase in menstrual cycle abnormalities. Now, more research has come out indicating that there might be a link between exposure to COVID vaccines and changes in menstrual cycle phase. The study, which was publishe in the journal Biological Psychiatry,

look at data from over 9,000 women who took part in the Vaccine Adverse Events Reporting System (VAERS) between 1996 and 2016. Analyses reveale that exposure to any of seven adjuvants use in COVID vaccines – aluminum hydroxide, formaldehyde, hydrosyl mercury sulfide, neomycin, polysorbate 80, squalene oil. And thimerosal – was associate with a statistically significant increase in reports of menstrual cycle irregularities such as early onset of menstruation or altere periods. While this isn’t proof that these vaccines caused these changes, it does suggest that further research is warranted into their potential links. So if you’re worrie about possible side effects from your COVID vaccination – or any other vaccine for that matter – speak to your doctor before making any decisions.
