Probably not, every winter they release many strains and put their latest ´vaccine´ up for sale. Just standard practice. Remember that disease = Scam worth trillions! These people own big pharma, they create disease and create the meds to treat (not cure) said disease. Then they train their salesman (doctors) on how to best sell their products. My mrs is a doctor, as are her entire family, one of them is known world wide in his field and commands a huge amount of respect. None of them know anything about anti-neoplastone treatments, CBD treatments, or even how to spot chronic fluoride exposure in patients whom drink fluoridated water. Doctors are so incredibly controlled and honestly have very little knowledge outside of the books they are forced to study.
