Until late in the season flu shots only really help with flu from previous years. The new varieties require time to have vaccines developed.
You do not understand flu vaccine production. The strains are chosen before the beginning of the season, and then production begins. The vaccine for the entire season contains the same strains. The vaccine for the previous season expires June 30 of the next year, e.g. the vaccine for 2018-19 will expire June 30, 2019.

what an odd and hilarious post. I was going to suggest wearing one of those pink hats.

the snark was strong. And then it went on to a bunch of criticism.

Great way to drive all the pro vaccers to the Sacramento forum.

That is my point. The vaccines are for the ones that hit before the season starts. New ones appear after the season starts and no vaccines are available for quite a while.

New ones are available before the predicted start of the season.

New flu virus' appear after the start of the season and thus no vaccines can be available.


Also:


You may be exposed to a flu virus that is not included in the seasonal flu vaccine. There are many different flu viruses that circulate every year. A flu vaccine is made to protect against the three or four flu viruses that research suggests will be most common.


https://www.cdc.gov/flu/prevent/keyfacts.htm


This shows changes are even occurring now.


https://www.cdc.gov/flu/season/flu-season-2019-2020.htm


The effectiveness of the flu vaccine depends in part on how well the viruses included in the vaccine match what’s in circulation.

During the past two seasons, the vaccine was about 40 percent effective, according to the CDC.


This season looks much better.




Plus:


Taylor Swift once sang, "Are we out of the woods yet? Are we out of the woods? Are we in the clear yet?" She probably wasn't singing about this year's flu season. But if she had been, the answer would be "No, no, and no." The flu season is not over. In fact, there's now a new potentially nastier strain of the flu virus making the rounds.

Your claim was that the seasonal flu vaccines are not ready until after the season starts. That is not true. The composition of next season's vaccine has been determined, and barring any hitches in production will be available in September, prior to October, when the season usually starts. Unless a pandemic develops no new vaccines are produced midseason, no matter whether there is a vaccine mismatch or not.

Your article is from a month ago. This season has lasted longer than average but it is winding down now.

You misunderstood my comment.



The ones produced are for some (3 to 4) of the viruses that already were known about, but not for any new one that appears. Your last line is what I was speaking about.



New ones that appear after the season starts need time to be evaluated, tested, and a vaccine produced.



The flu vaccines do NOT cover all existing viruses nor can they cover new ones that appear. Fortunately new ones starting after the beginning of the season, are rare.

They do not make a new vaccine in mid season, even if the vaccine for the season does not match the dominant circulating strain(s). It is just not practical to do that. The exception is during a pandemic, when there are large numbers of infections worldwide with a new strain. That was done in 2009.

Ever since then I get nervous whenever I see a pig sneeze.

I wouldn't worry so much about the anti-vaxxers. At some point their numbers will decrease abruptly.
