original antigenic sin #OAS deals with antibodies and might be important for protection from infection and herd immunity.

T-cell immunity might be key to protect from (serious) disease by eliminating infected cells and yielding cross-protective immunity. 1. Vaccine for T-cells protects from moderate-severe disease.
2. CD4, CD8 epitopes crucial for cross-protection against sever disease.

💉Why are mRNA vaccines so effective?

After decades of trying to make mRNA stable enough to elicit immune responses they seem to outcompete all other vaccines:

My first thought was that #Ukraine would not stand a chance against #Russia in the lowlands, but #Putin dismantled the Russian army from information, GPS, gas and food.
The invading army is unprepared, similar to operation #Barbarossa.

https://twitter.com/nexta_tv/status/1498181493683802112

Lessons from other wars show that understanding how the army is welcomed, local information, supply chains of gas and food are crucial for the military success. In general these are hard to manage in the mountains, but there are already challenges in the lowlands.

Testen, vooral in de context van bron- en contact onderzoek #BCO is de standaard en efficiëntste manier virus epidemie bestrijding.
