Even if you do get the vaccine, there's no guarantee that it will actually include your new virulent strain.
True, for reference look at this table from the CDC:
https://www.cdc.gov/flu/professionals/vaccination/effectiveness-studies.htm https://www.cdc.gov/flu/professionals/vaccination/effectiven...
2011-12: 47% vaccine effectiveness
2012-13: 49% vaccine effectiveness
2013-14: 52% vaccine effectiveness
2014-15: 19% vaccine effectiveness
2015-16: 48% vaccine effectiveness
2016-17: 42% vaccine effectiveness
But I still get my flu shot every year, better to be 40-50% protected than 0%.
- lr4444lr 9y agoAre you sure the R0 of the original article isn't determined accounting for the fact of vaccine ineffectiveness?
- exhilaration 9y agoI don't know, corrections are welcome!
- btilly 9y agoThe R0 of the original article is determined on the assumption that nobody is immunized at all. Vaccine ineffectiveness is the odds that when you are potentially infected by a wild flu, the virus that you encounter was one that you were vaccinated against. Vaccines are more effective when they correctly predict what varieties of flu will be circulating. But the more effective the immunization program, the more the ones that they predicted become and the less effective the vaccine becomes. However we all benefit because less flu is in the environment.
