FluMist vaccine recommendation – CDC gets the science right

FluMist vaccine recommendation

There are a lot of anti-vaccine tropes about the CDC (Centers for Disease Control and Prevention), none of which make a lot of sense. There’s the conspiracy theories that the CDC is bought off by Big Pharma. Or the CDC whistleblower meme that they hid evidence that vaccines cause autism. However, the CDC usually gets the science right, like they did with the recent FluMist vaccine recommendation.

The CDC, a federal government agency made up of scientists, physicians, and public health officers, who come from civilian and military backgrounds, are the first responders to almost any infectious disease outbreak across the world. They are the front line of science against disease.

They use scientific data, gathered through clinical trials or lab experiments, to make public recommendations about diagnosing, treating and preventing diseases. They’re impartial about their recommendations – they go where the data leads them.

So what’s the story behind the FluMist vaccine recommendation, better yet, non-recommendation? It’s not all that complicated, and it’s clear that the CDC got the science right. Continue reading “FluMist vaccine recommendation – CDC gets the science right”

Chicken vaccine viruses recombine in wild, anti-vaccine conspiracies abound

For the past five years, there have been large outbreaks of infectious laryngotracheitis (ILT) in chickens in Australia. ILT is a highly contagious herpesvirus, and one of a group that includes herpes and chickenpox. The chickens become very ill with red and swollen eyes, along with sneezing, coughing and gasping, while occasionally producing a bloody nasal discharge. Mortality is quite high, and surviving chickens produce fewer eggs, which, of course, is very bad for chicken farmers.

The diseases are usually prevented by a vaccine against ILT. Many vaccines against viruses, including the ILT version, contain live attenuated viruses (LAV), which are viruses that have reduced virulence, though still alive, so that the immune system recognizes it to develop an immune response. Attenuation takes an infectious agent and alters it so that it becomes harmless or less virulent.
