Currently, the Pfizer-BioNTech vaccine is the only shot with a booster dose authorized for people 65 years of age or older or who are at high risk of serious illness because of an underlying condition or their job.

Immunocompromised Americans may also be given a booster dose, as can the third shot of Moderna’s vaccine.

As of Tuesday, 7.8 million doses of the COVID-19 vaccine booster have been distributed, official data from the Centers for Disease Control and Prevention (CDC) shows.

A vast majority, 6.2 million, belong to Pfizer Vaccine, although only 1.5 million doses of Moderna Booster have been distributed.

Some of these shots are unauthorized, being given during routine check-ups by primary care physicians and other doctors.

Moderna, based in Cambridge, Massachusetts, is now pushing to distribute its boosters as widely as Pfizer, and has expanded eligibility.

Moderna’s booster shot will be discussed by an FDA advisory panel on Thursday.

Booster shots for the Moderna vaccine were expected to roll out on September 20 to all Americans age 18 or older.

The White House announced in late August that both Pfizer and Moderna Vaccines would have boosters available in late September, pending approval from regulators such as the FDA.

Despite the declining effectiveness of vaccines, injections are still considered effective in preventing hospitalization or death.

Because of this, regulators did not approve the shots until the September 20 deadline, and even when the Pfizer booster was finally authorized, it did not receive full approval for all Americans, aimed at White. House was.

Meanwhile, J&J only makes the one-shot vaccine available in the US, and is hoping to receive authorization for other shots later this week.

The company reports some rare side effects such as blood clotting or swelling in the heart in people receiving the booster, but not to the extent that it believes the shot is unsafe.

Authorization for second shots of J&K vaccine will be discussed by the advisory panel on Friday.

The Pfizer vaccine — unlike the other two — is also available for minors between the ages of 12 and 17.

More than 150 million doses of the two-shot Moderna vaccine have been used in the US since the shot was authorized in December — Pfizer trailing the shot by 80 million — and Johnson & Johnson administered 15 million doses. Has been.

Nationwide, 65 percent of Americans have received at least one dose of a COVID vaccine, and 56 percent are fully vaccinated.
