(NEXSTAR) – With the rapid spread of Delta variants in the United States and other countries, you may be wondering if shots from another manufacturer can boost your immunity.
On Monday, the World Health Organization’s Chief Scientist, Soumya Swaminathan, warned against mixing and matching different COVID-19 vaccines.
“It’s a bit dangerous here,” Swaminasan said in an online WHO briefing on Monday. “When citizens begin to decide when and who will take the second, third and fourth doses, the country will be in a chaotic situation.”
The WHO statement has caused turmoil in some parts of the world, including Canada. Canada has adopted a combined approach for healthcare providers to vaccinate residents against COVID-19.
Ontario Health Minister Christine Elliott Spokesperson Said in a statement “Ontario has recommended that mixed vaccines be safe, based on studies in the United Kingdom, Spain and Germany that found that mixed vaccines produce safe and strong immunity (NACI). ) Continues to follow the advice. Response. “
Later Swaminasan Revealed on Twitter “Persons shouldn’t decide for themselves, public health agencies can make decisions based on available data,” he added, adding that health officials are still waiting for the results of mixed-and-match studies using different vaccines. It was.
Dr. Peter Chin Hong, an infectious disease expert at the University of California, San Francisco School of Medicine, said her words came from a public policy perspective, not personal advice, “to avoid unregulated confusion. “. Especially in countries where vaccines are not easily accessible.
“I think the first thing she thought she made a mistake in her comment was that she said she didn’t have the data, but she did,” Chin Hong said. British researchers And other European countries have found that mixed doses from different manufacturers work as well when it comes to protection from COVID-19.
“Don’t do it if the party line doesn’t need to be combined, but if you do it for any practical or operational reason, it’s okay,” said Dr. Chin Hong.
Allowing healthcare providers to mix and match doses can streamline the vaccination process in countries suffering from vaccine shortages.
In the United States, the CDC has not given full approval until further investigation is conducted. However, in January, the CDC updated its guidance, stating: In rare situations Moderna can be shot at least every 28 days after someone receives a Pfizer injection.
What if I get the Johnson & Johnson vaccine?
There are reports of people receiving a single dose of Johnson & Johnson vaccine looking for mRNA “booster” shots of the Moderna or Pfizer vaccine to boost immunity. Tweet about the experience..
“I don’t know if mRNA boosters (or two doses of J & J) will significantly enhance protection, but boosters can work against almost any other vaccine,” said Angela Rasmussen. The doctor says. I have written.. “But you shouldn’t wait for suggestions on this. In the United States and increasingly Canada, there is ample supply of mRNA vaccines that expire before shipping to other countries.”
The Johnson & Johnson vaccine has been found in clinical trials to be 66.3% effective in preventing COVID-19 infection. CDCThis was lower than the 94-95 percent reported for mRNA vaccines. However, the vaccine was 100 percent effective in preventing hospitalization and viral death.
Johnson & Johnson has Make a statement On July 1, the vaccine said it protected from COVID-19 and produced antibodies that were effective in neutralizing the delta mutant eight months after the shot was administered.
But is it safe to mix the viral vector J & J vaccine with mRNA vaccines like Moderna and Pfizer?
“I’m not worried about getting Pfizer or Moderna after J & J,” Chin Hong said. “It’s very different. It’s not like saying” get Astra Zenca after J & J “. Because it’s similar.However, Pfizer and Moderna are not really associated with any of these autoimmune conditions. Guillain-Barré Syndrome Like Nervous Syndrome Or Rare blood coagulation event.. This is a very specific side effect, very rarely related to vector vaccines, but not to mRNA vaccines. “
He added that people who have been vaccinated with the J & J vaccine are “very unlikely” to experience either of the two side effects more than three weeks after the injection.
When it comes to looking for multiple shots of the COVID-19 vaccine from different manufacturers, Chin-Hong says there is a theoretical risk of overdoing it.
“In terms of restrictions, I probably won’t get too many vaccines,” he said. “Every time you get a vaccine, your chances of immune activation will increase. So for now, two or three seem to be fine, but above a certain threshold, there are so many in the body. Immune cells can enter and start attacking your body, so you need to worry about safety beyond a certain point. “
Chin-Hong added that few people received three or more doses and that no such immune response was recorded.
