The CDC has discovered that reactions to the COVID-19 booster dose are identical to those to the first dose.

The Centers for Disease Control and Prevention stated Tuesday that side effects recorded among recipients of a COVID-19 booster vaccine are identical to those seen after the second dose.

The findings are based on submissions to the CDC’s voluntary vaccine safety surveillance program, which tracks shot side effects, from around 12,600 booster-dose participants.

The FDA approved booster doses of the Pfizer-BioNTech and Moderna vaccines for solid transplant recipients and those with impaired immune systems in August, but booster shots are still being examined for the majority of people.

Last Monday, the Food and Drug Administration advised third, booster doses of the Pfizer-BioNTech vaccine for individuals 65 and older, as well as those with chronic health conditions such as diabetes and heart disease, who are at higher risk for severe COVID-19.

However, the FDA has not yet advised extra doses for the Moderna or Johnson & Johnson vaccines, despite the fact that both companies are conducting clinical trials to establish the safety of boosters and whether they are needed.

“Recommendations for an extra dose of COVID-19 vaccine were confined to patients with moderately to severely immunocompromising diseases who had received two doses of an mRNA vaccination during the period covered by this study,” the agency researchers said.

According to the statistics, 79 percent of the 12,600 booster users in the study reported having injection-site responses, such as discomfort and swelling.

In addition, 74% reported weariness, muscle discomfort, or headaches after receiving the third dose, among other “systemic” effects, according to the agency.

These findings are similar to those reported after the second dosage of the vaccinations, when slightly under 78% reported injection-site responses and nearly 77% reported systemic adverse effects.

The CDC researchers wrote, “No unexpected patterns of adverse responses were identified.”

“Those reported were mild to moderate and transient,” they said, implying that symptoms went away on their own.

Between Aug. 12 and Sept. 19, more than 22,000 persons received a booster dose of a COVID-19 vaccine – either the two-dose shots from Moderna and Pfizer-BioNTech or the one-dose Johnson & Johnson vaccine – according to the CDC.

According to the CDC, however, not all of them provided information on negative effects they experienced after receiving the booster.

The Moderna or Pfizer-BioNTech vaccines were administered to the great majority of booster dose users,… Article Summary from Nokia News
