COVID-19 Vaccine Updates
- Having an undetectable viral load when on HIV treatment (ART) also stops HIV transmission
- For > 20 years it is known that ART reduces HIV transmission but now it is clear that the risk is not just reduced but stopped completely.
- ART protects your partners.
- You don’t need to use condoms if you were only using them to stop HIV provided you take ART every day and have undetectable viral load for at least three months and continue to take meds without missing doses.
- The evidence for U=U comes from studies with both gay and straight couples, and for all types of sex.
- There should be no doubt that a person with sustained, undetectable levels of HIV in their blood cannot transmit HIV to their sexual partners.
