AURORA, Colo. (CBS4) – The CDC says people who have been fully vaccinated against COVID-19 don’t need a booster vaccination – yet. Even if you got your vaccination months ago, you will still be protected and COVID symptoms will be much less severe even if you get the Delta variant. However, this does not mean that we will never need a recording again.
“We know that immunity wears off over time. I had my first vaccination in December. I’m probably less immune to COVID than I was three months ago. That being said, I’m probably sufficiently immune to COVID, ”said Dr. Richard Zane, Chief Innovation Officer at UCHealth.

Pfizer found that the effectiveness of its vaccine decreased by an average of 6% every two months. The effectiveness in groups such as the elderly and immunocompromised will decline faster.
Some people get a third shot anyway and take boosters themselves.
“The real downside is that you could have the same side effects as after the second dose, such as fever, muscle pain and malaise,” said Zane. “You could very well be better protected. The question is, do they need better protection? “
Some countries have already approved boosters for people who were most at risk for COVID. Pfizer said it would begin clinical trials of the booster next month while they seek regulatory approval for a third dose.

Vaccine manufacturers are formulating a new vaccine that targets mutations.
“The only option we have now is to give people the same vaccine they already have. Companies are developing boosters that take changes in the virus into account, such as the Delta variant. Ideally, any time, a year or five years, when you need a booster vaccination, the vaccination takes into account any differences in variance and viruses, ”Zane said.
What worries doctors most now is the consequence variant. This would be a mutation of COVID that current tests cannot test for, the drugs currently used to treat it are not working, and the vaccines will not work.
“Vaccination is about protecting yourself, protecting society and building a wall between the virus and humans. When the virus gets into unvaccinated people, they mutate, ”Zane said. “We will have COVID forever at our current vaccination rates and the unvaccinated are causing this.”
Zane says we’ll probably need another shot. Until then, he will continue to visit patients who wish they could have their first.

“I see the realization and desperation for the vaccine before my eyes because people are sick with COVID like dogs,” said Zane. “Some patients still don’t believe it is COVID.”
