Pfizer/BioNTech’s COVID-19 Vaccine Formulation Tweaked to Improve Stability

With the release of its pediatric COVID-19 vaccine, Pfizer switched the buffer used in its formulation to increase the stability of the product, allowing it to remain at refrigerator temperatures for longer. The Food and Drug Administration OK’d the change, which is also being made to some doses for teens and adults. Social media posts, however, misleadingly suggest that the ingredient swap is dangerous or was added to prevent heart attacks in children.

Colorado Order Addresses Surge in Hospitalizations, Not Vaccination Status

Responding to a surge in COVID-19 hospitalizations, Colorado Gov.

After getting the COVID-19 booster on Oct. 27, California Gov. Gavin Newsom canceled a trip and did not participate in any official public events for 12 days.

The COVID-19 death rate for unvaccinated people has been significantly higher than for vaccinated people in both Israel and the U.S. Despite that, conservative commentator Ben Swann makes the false claim in a video that Israeli data prove vaccines aren’t effective in preventing hospitalizations and deaths.

More than 70% of Japan’s population has received the COVID-19 vaccines, and the government is moving ahead with a booster shot in December. But a conservative radio host in the U.S. falsely claimed, “Japan drops vax rollout, goes to Ivermectin.” Japan hasn’t stopped its vaccine program and hasn’t approved ivermectin as a COVID-19 treatment.

Why It’s Easy to Misinterpret Numbers of Deaths Among the Vaccinated

Raw numbers of hospitalizations or deaths among those who are vaccinated are not a good indicator of whether vaccines are effective.

FEMA Staff and Contracted Medical Workers Are Required to Follow Vaccine Mandate
