With Gift Aid, your generous donation of £10 would be worth £12.50 at no extra cost to you.

I am a UK taxpayer and I understand that if I pay less Income and /or Capital Gains Tax than the amount of Gift Aid claimed on all my donations in the relevant tax year, it is my responsibility to pay any difference.

In our 35th year we’re asking people to donate £35 – that’s just £1 for every year we’ve been providing life-changing information. Any donation you make helps us continue our work towards a world where HIV is no longer a threat to health or happiness.

  • £5 allows us to reach millions of people globally with accurate and reliable resources about HIV prevention and treatment.
  • £10 helps us produce news and bulletins on the latest developments in HIV for healthcare staff around the world.
  • £35 means we can empower more people living with HIV to challenge stigma with our information workshops, videos and broadcasts.

Pre-exposure prophylaxis involves people who do not have HIV taking antiretroviral drugs when they are at risk of exposure to HIV in order to prevent infection. The drugs are usually taken as pills (oral PrEP).
