Are people who are vaccinated for smallpox

Agency officials and local health systems have since confirmed other children who were close contacts of monkeypox cases have also been offered shots.
Spokespeople for the FDA and CDC have declined to confirm how many requests have been granted for the use of the vaccine in children.
A spokesperson for Bavarian Nordic declined to offer details about whether it planned to trial the vaccine in children, but did say it planned to collect data on CDC's use of the shots.
protected against monkeypox?
While people in the current outbreak are now being vaccinated with vaccines initially designed to combat smallpox, like ACAM200 or Jynneos, officials have cautioned that Americans who were vaccinated for smallpox decades ago are unlikely to be protected from a monkeypox infection.
Though the U.S. stopped routine mass vaccination against telegram database smallpox in 1972, the CDC still recommends that scientists who are at risk of exposure because they work with orthopoxviruses — including monkeypox — in the lab get revaccinated every three years.
In the current outbreak, the CDC says some cases had been vaccinated against smallpox "decades prior." And in the 2003 outbreak, CDC researchers did not find evidence that previous smallpox vaccination — among those infected — reduced the odds of patients facing severe disease or being hospitalized.
"We do expect that people who have received the vaccine, even as children, will have some remaining immunity. But that is something that we're very interested in looking at, closely monitoring during this outbreak, to really define exactly how long that protection lasts and how much benefit people who have received vaccination many decades prior may still receive," said the CDC's Brett Petersen said on June 30, in a webinar with clinicians.
