After Pfizer FDA Clears Boosters for Moderna

Following the approval of a third Pfizer / BioNTech shot in September, the FDA has approved booster doses for the Moderna and Johnson & Johnson COVID-19 vaccines. The CDC also announced today that eligible people who are already wholly vaccinated would be able to get a booster dose of any of the three vaccines, regardless of which one they started with. In addition, the FDA approved third Moderna shots for vulnerable individuals, including people 65 and older, those at high risk of severe disease, and those at high risk of COVID-19 exposure at work, similar to the Pfizer / BioNTech booster.

The Moderna vaccine booster, on the other hand, will be a half-dose. Both vaccinations are mRNA vaccines, which include little bits of coronavirus genetic material. However, the Moderna vaccination offers a higher dose: 100 micrograms against 30 micrograms in the Pfizer / BioNTech vaccine. A third, 50 microgram half-dose of the Moderna vaccine, according to the manufacturer, could have fewer adverse effects while still providing adequate protection.

According to research, the Moderna injections provide longer-lasting protection against COVID-19 infection than the Pfizer / BioNTech shots — they remain effective months after the initial two-shot series. In contrast, the BioNTech shots’ efficacy appears to decline. Both have considerable resistance to hospitalization and mortality. Therefore, the FDA allows everyone who received the Johnson & Johnson vaccine to receive a second booster dosage.

Unlike the Pfizer / BioNTech and Moderna boosters, which require a six-month delay, the Johnson & Johnson vaccination can begin two months after the initial dose. In addition, the Johnson & Johnson injection was initially approved as a one-shot vaccine, which experts anticipated would make it easier to distribute to low-resource areas and provide to patients who would not want to return for a second shot logistically.
