We’re likely to feel the effects of Covid-19 for years to come. The Chief Executive officer of Pfizer, Albert Bourla, just revealed his thoughts on additional vaccine dosages, and judging from his predictions, it seems we’ll have to keep our guard up for quite some time. 

According to Albert, it’s likely that people will need a third dosage of the Pfizer vaccine after being fully vaccinated for about a year, but that remains to be seen.

He also predicted that we could possibly need an annual Covid-19 vaccine, much like the flu vaccine. However, that too is just a prediction at this time. 

“A likely scenario is that there will be likely a need for a third dose, somewhere between six and 12 months, and then from there, there will be an annual revaccination, but all of that needs to be confirmed,” Albert said during an event with CVS Health, according to CNBC. “And again, the variants will play a key role.”

While vaccines are seen as a necessary step towards progress and fighting off the virus, there is still so much that remains unknown, including its side effects.

Kathryn Clancy, the head of the Clancy Lab at the University of Illinois, is currently researching the side effects the vaccine plays on menstrual cycles, as some people have experienced irregularities. 

According to the Cleveland Clinic, another cause for concern is an increase in mammogramsshowing swollen lymph nodes after being vaccinated.

An increase in lymph nodes can indicate breast cancer, and while the vaccine doesn’t necessarily cause cancer, it will certainly put women on high alert. 

OB-GYN Kelly Culwell, MD, did reveal to Refinery29 that lymph nodes are often a result of vaccines, and it means that your body is producing antibodies in response. 

If you have any questions or concerns, do consult your doctor as soon as possible. Since so much is up in the air, the CDC recommends people read up on facts vs. myths about the vaccine and what to do after being fully vaccinated. Stay safe, everyone.  -AP
