It is my understanding that today’s flu vaccines have efficiencies way higher than that, around 70-80%. Vaccination is also not only to protect the vaccinated people from getting the virus, especially when we are talking about a pandemic, but to actually stop the virus from spreading in a population. That’s achieved by vaccinating 40/80%, depending on whether or not additional measurements (see above) are also rolled out.
