Will We Need to Vaccine Against Covid-19 More Than Once?
- 3 years ago
There are a lot of questions regarding the new vaccine against Covid-19 that has been approved and is now rolling out.
Indeed, the most asked question lately is how often will we need to be vaccinated against the new Corona virus?
At this stage, we still don’t know if one shot of vaccine will be enough to keep us immune for years. This lack of knowledge comes from the fact that the approved vaccine has been developed and trialed in a really short timeframe.
Scientists are still waiting to discover how long people vaccinated during the trial are immune.
Pfizer spokesperson stated that the question of how often people will need to be vaccinated is still to be answered and that trial participants are being monitored for another 2 years after the second dose being administrated.
Another important matter with the vaccine is to address potential mutations of the virus. Experts already expressed concerns about a mutation due to immune selection pression.
In that case, we will indeed need to be vaccinated every time the virus changes.
