2 Shots of the Pfizer COVID-19 Vaccine May Not Be Enough

It turns out that one or even two shots of the Pfizer COVID-19 vaccine may not be enough to protect you from the virus long-term. At least, that’s what Pfizer CEO Albert Bourla is quoted as saying.

During an event with CVS Health back on April 1, 2021, Bourla said a 3rd shot of the Pfizer vaccine may be needed within 6 to 12 months of the 2nd shot in order to stay protected against the virus. Moderna has also announced that they are currently testing a COVID-19 booster shot that would essentially act as a 3rd vaccination.

Because clinical trials for the vaccine were rushed, COVID-19 researchers still don’t know just how long and how well a 2nd COVID-19 shot can keep someone protected. Some doctors suggest that Americans may need to get an annual COVID-19 shot going forward, similar to how we treat the flu.

At the same time, the CDC is closely monitoring how the existing COVID-19 vaccines interact with "variants" of the virus that have developed in various parts of the world. So far, there is no known variant of COVID-19 that appears to be immune to the vaccines. However, much like the vaccines themselves, only time will tell just how resilient they are.

It's unclear how the public will react to news that their 2nd COVID-19 shot may not be their last, or how many of those considered "fully vaccinated" will be open to the idea of yet another shot.

Meanwhile, an investigation continues into the Johnson & Johnson COVID-19 vaccine and it's potential connection to 6 cases of a rare blood clot that killed one woman and put another in the hospital. The US government has paused administration of the vaccine until the investigation is complete.
