Flu vaccine shows low effectiveness against the main circulating strain this
season.
New research from Public Health England in UK has found that the seasonal influenza vaccine has provided low protection this winter against flu infection caused by one particular subtype, H3N2. This is because of a mismatch between the A(H3N2) strain selected for the vaccine this year and the main A(H3N2) strain that has been circulating in the UK this winter.
The UK findings follow the recent publication of the US and Canada’s mid-season vaccine effectiveness estimates, both of which also revealed the vaccine had unfortunately provided little protection against circulating A(H3N2) viruses this season in these countries. This was also linked to drift observed in H3N2 viruses.
It is not possible to fully predict the strains that will circulate in any given season and so there is always a risk of a drift occurring.
In addition to the occurrence of virus drift and hence its low effectiveness, concerns regarding vaccinations continue to increase in light of all of the information and documentation that has surfaced over the past few years.
There has been some medical research that indicates the many dangers associated with vaccines. For example, the vaccine-autism debate has been going on for years. There are a number of studies that link vaccines to a possible autism connection. And it is known that vaccine manufacturers suppress harmful data regarding their product.
