That talk is not unusual we have had several similar and I remember at the hight of the pandemic talk was Jehovah made the vaccines available how wonderful he is, these vaccines are from Jehovah
the GB updates really aggressively pushed them having experiences of sister with cleaning jobs and only fully vaccinated could keep their jobs and all the sisters thanked the GB for letting them know the vaccine is safe and effective
another experience showed some brothers in South America who were worried that the vaccines were not safe but the GB updates put their mind at rest that these vaccines were from Jehovah and they are safe and effective.
now JWs are still going to get their boosters to remain fully vaccinated every six months or so and another sister in our cong has damaged her health by following the direction even though she didn’t want to keep getting these boosters
until they do a U turn on the direction everyone has to keep getting their latest booster shots because once you have gone longer than six months you are no longer fully vaccinated
