COVID-19 has a knack for rebounding just as life starts to reopen a bit more in New York City.

But a coronavirus surge has also snuck up on New York City like a panther.

Those places are also less vaccinated than New York City, but one in four people still haven’t taken their shots in the five boroughs.

This year in New York City, the unvaccinated have experienced a rate of 266 cases per 100,000 people.

Compare that against 40 cases per every 100,000 who are fully vaccinated.

Look at hospitalizations, and it’s 21 for every 100,000 unvaccinated versus 2 among the same amount of inoculated people.

And when it comes to hospitalization, Americans relying on natural immunity were five times as likely to experience a COVID hospitalization relative to vaccinated people.

Fully vaccinated people are also less likely to spread the coronavirus in the rare cases where they experience a breakthrough infection.

study showed the noses of unvaccinated people excreted the virus for up to nine total days, while for fully vaccinated people, it was only four days.

“These are the people who are most likely to have a severe complication from COVID, even if they're vaccinated,” Dr.

At the quickest, it takes 21 days to receive two shots of Pfizer or Moderna vaccines, then your immune system needs to incubate for two weeks to be fully vaccinated.

So if you’re worried about a contagious person showing up for dinner, then your guests will want to take a COVID-19 antigen test the day before and the day of your gathering.

“The day that a person is contagious, that day those antigen tests are positive,” Dr.

Griffin said these antigen tests are very accurate during the period of time when a person is able to spread the virus to others.

This extra sensitivity means PCR tests are better at identifying people who are not yet contagious.

In September, health reporter Caroline Lewis wrote a helpful guide for finding these tests in New York City and what you might pay.
