AIDS besiegen: MIT stellt neue Impfmethode vor, die HIV mit nur zwei Impfungen abtöten könnte | MIT-Forscher haben herausgefunden, dass die erste Dosis das Immunsystem vorbereitet und ihm hilft, eine Woche später eine starke Reaktion auf die zweite Dosis hervorzurufen.

From the article: One major reason why it has been difficult to develop an effective HIV vaccine is that the virus mutates very rapidly, allowing it to evade the antibody response generated by vaccines.

Several years ago, MIT researchers showed that administering a series of escalating doses of an HIV vaccine over two weeks could help overcome a part of that challenge by generating larger quantities of neutralizing antibodies.

However, a fast multidose vaccine regimen is not practical for mass vaccination campaigns.

In a new study, the researchers have found that they can achieve a similar immune response with just two doses, given one week apart.

The first dose, which is much smaller, prepares the immune system to respond more powerfully to the second, larger dose.

Yep these guys are gonna disappear, die mysteriously, or discover other interests.
