Infectious disease specialist at the University of California, San Francisco, Dr. “There’s a lot of unknown about it, whereas the vaccine is known – that’s my caveat,” said Peter Chin-Hong. “Of course I wouldn’t put all my eggs in the previous infection, natural immunity basket.”
As with the protection provided by vaccines, immunity to natural infection can weaken over time, making children susceptible to re-infection. Dr. “I would like to know when this infection happened,” Chin-Hong said. “If it was a year or so ago, I would have worried about reduced immunity.”
What You Need to Know About Covid-19 Booster Shots
The FDA has allowed booster shots for millions of buyers. Pfizer-BioNTech, modern and Johnson and Johnson vaccines. Pfizer and Moderna recipients who qualify for support include people aged 65 and over and young adults at high risk of serious Covid-19 due to medical conditions or where they work. Eligible Pfizer and Moderna recipients can receive a boost for at least six months after their second dose. All Johnson & Johnson recipients will be eligible for a second shoot at least two months after the first.
Yeah. The FDA has updated its mandate to allow medical providers to empower people with a different vaccine than the one they originally received. “Mix and Match.” You can get a booster for any other vaccine, whether you’ve received Moderna, Johnson & Johnson, or Pfizer-BioNTech. The regulators did not recommend any vaccine over the other as a booster. They also remained silent on whether it would be preferable to stick to the same vaccine whenever possible.
The CDC said conditions that qualify a person for a booster shot include: hypertension and heart disease; diabetes or obesity; cancer or blood diseases; weakened immune system; chronic lung, kidney, or liver disease; dementia and some disabilities. Pregnant women and current and former smokers are also eligible.
The FDA has allowed boosters for workers whose jobs put them at risk of exposure to potentially infectious humans. The CDC says the group includes: emergency health workers; education workers; food and agricultural workers; manufacturing workers; correction workers; US Postal Service employees; public transport workers; grocery workers.
Yeah. The CDC says the Covid vaccine can be administered regardless of the timing of other vaccines, and many pharmacy sites allow people to schedule a flu shot at the same time as a booster dose.
Dr. Bhattacharya said that innate immunity in adults generally “seems to hold up well.”
However, it is unclear whether the protection seen in adults extends to children, as most children tend to have milder symptoms than adults and may not have developed a full-blown defense against the virus.
Natural immunity in children may also not be able to withstand the variants. Several studies have shown that just one dose of the vaccine in a previously infected adult can turbocharge protection even against variants such as Beta and Delta.
Dr. “I suspect this will be the case with children as well,” Hensley said.
The vaccine should also reduce the chance of a reinfected child passing the virus to others who may be susceptible to serious illness. Dr. “If someone in your household is extremely vulnerable, the consequences are pretty bad,” Bhattacharya said.
I’m worried about side effects. Is the vaccine safe?
All the evidence so far shows that vaccines are much safer than a Covid disease, even for children.
For example, although the vaccines have been associated with the possibility of myocarditis, heart inflammation, which is rare in young men, most of them quickly resolved symptoms. A much more severe version of Covid that is much more likely to cause myocarditis.
