![]() As with the previous paper, the studies relied on the self-reporting of condom use. Data were included on a total of 3262 participants (different inclusion and exclusion criteria were used from the previous analysis). The researchers conducted a new meta-analysis of four studies: the two previously mentioned studies as well as JUMP-START and the HIVNET vaccine preparedness study, each conducted in the mid-1990s. In 2018, Dr Wayne Johnson and colleagues, also from the CDC, published a new analysis with different findings. While condomless sex with an HIV-positive top (insertive partner) is more risky than condomless sex with an HIV-positive bottom (receptive partner), in this study infection rates were not statistically different between receptive and insertive partners. Consistent use is challenging for many people: only 16% of men across the two studies reported always using condoms with all sexual partners over the year or more they provided data. However, for those who reported only “sometimes” using condoms, the studies showed that there was “minimal or no protection” from HIV, with just 8% of HIV infections prevented. 100% of the time), condoms prevented 70% of HIV infections. Both studies, conducted before the introduction of PrEP, recruited HIV-negative men who reported having sex with at least one HIV-positive partner.Īnalysis found that among those who reported consistently using condoms (i.e. In 2015, Dr Dawn Smith and three other researchers from the Centers for Disease Control and Prevention (CDC) looked at anal sex between men by analysing the results of two studies conducted in the USA: VAX 004 (a study of 4492 men between 19) and EXPLORE (a study of 3233 men between 19). Two recent analyses are worth highlighting. Condoms in combination with PrEP or undetectable viral loadĭo condoms protect against HIV when used by gay couples?.Do condoms protect against HIV when used by heterosexual couples?.Do condoms protect against HIV when used by gay couples?.The British Association for Sexual Health and HIV say that it is reasonable to suggest that the effectiveness of condoms against HIV when used reliably and consistently may be over 95%. Laboratory studies and product testing have shown that reputable condoms tested in the laboratory are completely impermeable to micro-organisms as small as viruses. You can read an overview of condoms here. To best protect against HIV they can be used in combination with other prevention methods such as pre-exposure prophylaxis (PrEP) or an undetectable viral load. Studies show that if used correctly, condoms offer strong protection against HIV, as well as having the added benefit of reducing the risk of other STIs. Protection rates can be significantly improved by combining condoms with other forms of prevention.Condoms can only protect against HIV and other sexually transmitted infections (STIs) if used correctly. ![]() Laboratory testing shows that condoms are impermeable to viruses, but protection rates are lower in real-world studies.
