Both Pfizer’s and Moderna’s vaccines for COVID have been widely used until now. But although both promise high efficacy against the coronavirus, it may not always happen that way.

According to Yahoo News, a recent report by the Centers for Disease Control and Prevention (CDC) found that the Pfizer vaccine is not doing too great at preventing severe COVID illness over the long term, compared to Moderna’s jab.

Only 77% efficiency against hospitalization due to COVID

Data were collected from 18 states from March to August. Researchers thus found that the Pfizer vaccine for COVID reduces the hospitalization risk by 92% within the first four months. While this indeed sounds great, the efficacy drops all the way to 77% after 120 days will pass from the vaccination.

As for the Moderna’s jab, it’s doing a lot better. Researchers found that the efficacy of this vaccine remains 92% effective after 120 days, meaning a decrease of just 1%.

The vaccine from Moderna seem to elicit higher levels of a key antibody than the jab developed by Pfizer, and Dr. Timothy Brewer pointed that out, as quoted by Yahoo News:

We know from other studies the neutralizing antibody levels will decay over time, so starting at a higher level will mean that you have farther to go before you decay to a point where efficacy drops off.

Dr. Robert Murphy, director of the Institute for Global Health at the Northwestern University, declared as also quoted by Yahoo News:

Based on the data I have seen, persons who received the Pfizer vaccine would benefit from a booster dose at this time,
I don’t see why we have to wait until the younger people get sick and become hospitalized.

Would you be more willing now to get vaccinated for COVID with the jab developed by Moderna? Let us know in a comment!
