With COVID-19 rising among vaccinated, health experts urge booster shots
Oct. 31—
Nearly a third of those hospitalized with COVID-19 in New Hampshire in recent weeks were fully vaccinated, according to the state health department.
Lori Shibinette, commissioner of the Department of Health and Human Services, said last week that breakthrough cases among those vaccinated for COVID-19 are rising, as immunity from the vaccines wanes amid the spread of the aggressive delta variant.
That makes it all the more urgent, public health leaders say, for eligible adults to get booster shots.
Over the summer, Shibinette said, about 90% of those hospitalized for COVID-19 were unvaccinated.
"We watched that start to change over the last two months, so it was about 80-20 in September and it's about 70-30 in October," she said at a media briefing.
"We would expect that as we get more boosters out, we're going to see that move again the other way," she said. "That's the hope."
The declining protection the data show for COVID-19 vaccines is similar to that seen with other vaccines, notably the flu vaccine, he said.
So which booster should you get
If you received a Pfizer or Moderna vaccination, you can either get the booster from the same manufacturer or you can switch. But Calderwood said there's no added benefit to getting a different booster. "If you got two Pfizers, then you do well with a third Pfizer," he said.
That's not the case with the one-shot Johnson & Johnson vaccine, however.
People who got the J&J vaccine will get the best continuing protection with a Pfizer or Moderna booster, which uses a different technology, called Messenger RNA (mRNA), from that in the J&J.
Getting a second J&J shot, he said, will provide about the same level of protection as the two-shot Moderna or Pfizer vaccines. But getting a Pfizer or Moderna booster instead, he said, will give you a higher level.
"So you're much better off, if you started with a J&J, switching to get your second shot with Pfizer or Moderna," he said.
But there are no data that indicate you should get a J&J booster if you got a Pfizer or Moderna vaccine, he said.
