This week, The Journal of Infectious Diseases published a study looking at the number of human papillomavirus infections in females before and after HPV vaccine was created (back in ’06). The study found impressive results: a 56% decrease in HPV since the vaccine was introduced in 2006 (among girls between 14-19 years old). This is a big deal [...]
Fifteen years ago The Lancet published a case study that erroneously suggested that there could be a link between the MMR vaccine and autism. That letter has long since been discredited, and back in 2010 The Lancet retracted the article. Anti-vaccine advocates have been pointing to that long-since discredited 1998 case study to argue that there [...]
This week the WHO announced that several people in eastern China are infected with a newly mutated bird influenza virus called H7N9. All are in critical condition and some have died... but importantly the cases don't appear to be linked- meaning it's probably not from human to human transmission (that's good). The World Health Organization website has more detail [...]
Whooping cough (pertussis) is a growing problem in the US and Arizona. There were 41,880 cases and 14 infant deaths from pertussis in the US last year… which is the largest number of cases since the vaccine became available in the 50s. In Arizona there were 988 cases in 2012 and there’s a pretty substantial outbreak going on right [...]
Just as our influenza season winds down (and it is), it's time to plan for the next one. Every February the World Health Organization convenes a panel of experts to look at the most current data on the circulating flu strains from around the world and makes recommendations for the next season’s Northern Hemisphere flu vaccine. [...]
Check out CDC’s new iPad App, Solve the Outbreak, which lets you pretend you’re a disease outbreak investigator in the world-class Epidemic Intelligence Service by solving outbreaks based on real-life. When new outbreaks happen, disease detectives are sent in to figure out how they started, before they can spread. You get to investigate the outbreak and [...]
As I mentioned in a blog post a few weeks ago, more AZ parents are choosing not to vaccinate their kids- and using “personal exemptions” when they enroll their kids in school. If the trend continues, we could jeopardize our immunization rates enough so that we'd see long gone diseases like measles and mumps return in [...]
During the 2009- 2010 influenza pandemic, we saw how influenza can be unpredictable in terms of who it affects most, when it occurs, and what strains will circulate. This season is no exception. While the circulating strains are exactly what we predicted, the peak of the flu season is hitting earlier than usual (now) and it's [...]
The CDC’s Advisory Committee on Immunization Practices released issued new recommendations to encourage pregnant women to get the whooping cough (pertussis) vaccine (Tdap) during their pregnancy. Since most kids get whooping cough from a close family member, vaccinating parents (and teens) is one of the best ways to prevent infants, especially those who are too young [...]
At the core- vaccines are really about community protection. Our public health system depends on a solid network of providers that are available to vaccinate kids for all of the nasty infectious diseases that have plagued humanity for millennium. It’s not just access to care and a solid network of providers that vaccinate that are [...]
