CDC updates COVID-19 vaccine guidelines after health workers have allergic reactions

Centers for Disease Control and Prevention have updated who should avoid taking COVID-19 vaccine or be careful.

The announcement comes after several health workers had allergic reactions to the vaccine. Reactions remain rare, but experts say it is essential that any serious symptoms be treated immediately.

CDC guidelines now say that anyone who has previously suffered an immediate allergic reaction of any severity to any ingredient in Pfizer or Moderna vaccines should not be vaccinated unless authorized by doctors.

One ingredient that is carefully examined is called polyethylene glycol. It is a compound that is used to stabilize and transport bubbles for vaccine messenger RNA.

It has never been used in a vaccine, but it is an ingredient in many medicines. The CDC also said that anyone with a polysorbate allergy should not receive the photos. It is an ingredient used to stabilize medicines, foods and cosmetics.

Polysorbate is not an ingredient in vaccines, but people who are sensitive to it may also be sensitive to polyethylene glycol.

Experts said people with severe food or drug allergies can be vaccinated. But they should be observed for 30 minutes after that, instead of just 15. They should also take a shot at a facility that can immediately treat an allergic reaction.

The CDC said anyone with a severe allergic reaction to the first dose of COVID-19 should not receive the second dose.
