They do prevent transmission, since they make people less likely to be infected, and if you're not infected with the virus you won't transmit it. The vaccines are somewhat less effective at preventing people from being infected at all than they are at preventing hospitalization and death, but still significantly effective. [1]

Intramuscular vaccines induce antibody production at nearby lymph nodes inside of the body; and these mRNA vaccines in particular also cause S-antibodies to circulate in one's blood (even though that's unintended and the long term effects are still unknown). Because the intramuscular route of administration, S-antibodies are not present in significant quantities inside the lungs of vaccinated individuals. Thus with covid-19 being an airborne disease, vaccinated people can still exhale virus-containing breaths and transmit the disease to others, who can then go on to contract the illness, whether they're vaccinated or not. So while the vaccines offer protection against serious illness to those who receive it, it certainly does not prevent transmission.

(And this is broadly corroborated by other studies) The consensus from studies is that, while not 100% effective at preventing tranmission, vaccines do reduce the transmission of Covid, even considering Delta (Omnicron is too recent for there to be data, but there's no reason to doubt transmission would also be reduced).
- mattrighetti 5y agoLower probability of getting infected != prevent infection. Lower probability of getting infected == lower probability of spreading the virus != vaccines prevent transmission.
- joshuamorton 5y agoPreventing transmission is not binary. Reducing the probability of transmission is preventing transmission, as it is preventing [some] transmission.
