If you have mpox, you know that you're in the clear when your lesions have healed and the scabs have fallen off. That's the best way.
Rather than giving a timeframe, it's more important to say, even the scabs could potentially transmit the virus, so you want to be completely healed and then your risk of transmission goes away.
Mpox vaccines are available … and FREE!
Vaccination is available at no cost regardless of your ability to pay the administration fee. Providers may bill insurance or Medicaid / Medicare. Your local health department can also provide information about options in your community.
