"We're offering free flu shots because confirmed cases of the virus continue to be a significant health threat throughout Pennsylvania".
Scully said the child was a student at Golden Hill Elementary School and said additional counseling staff were assigned to the school Tuesday morning and would be on call throughout the rest of the week. This does not mean that it kept 36 percent of the people who got it from getting sick at all.
Others question the vaccine's effectiveness.
"The H3N2 strain is the one that is more problematic, because those particular strains cause more severe illnesses and you see more deaths associated with them", Morrow said. That ties the highest level seen in the USA during swine flu in 2009.
The numbers are a snapshot taken in the middle of a frantic flu season.
New York State is also experiencing a historically devastating flu season. "That's higher than we typically see for H3N2", Belongia tells The Washington Post.
Children's vulnerability is of special concern this season.
"For the 2017-2018 season, manufacturers projected they would provide between 151 million and 166 million doses of injectable vaccine for the USA market".
Federal health officials say that, as they anticipated, the flu vaccine isn't very effective this year - but they say it has still prevented thousands of serious illnesses and deaths.
Though there were 516 influenza-like-illness cases reported at this time past year in the county, only 5,417 cases were reported statewide, a little more than half of this season's state total. There were 34 deaths reported between January 28 and February 3. The vaccine was only 25 percent effective against that type.
Health officials have confirmed the first flu-related pediatric death in MA.
The flu virus can also live for a short time on things you touch, such as door knobs, telephones, and toys. "Getting the flu shot is the same kind of sensible precaution as buckling your seat belt".

This flu season will likely go down as one of the deadliest in our state's history.
Many details about how the immune system fends off the virus and protects the human body remain unknown. Early detection could save your child's life.
It's not clear why the H3N2 component of the vaccine works so poorly.
"This flu season continues to be extremely challenging and intense", said Schuchat.
Most people with the flu will have a mild illness and do not need medical care or antiviral drugs.
"The vaccines that we have today are not the ones that we'd like to have in 10 years", she said. "Fairly minor differences in genetic changes can lead to really meaningful differences in how much protection the vaccine is providing". Manufacturers grow flu viruses in chicken eggs. The U.S. government, he said, should invest in research and large clinical trials that explore better ways to make flu vaccines. The CDC's midseason estimates of vaccine effectiveness against H1N1 is 67 percent and against B viruses 42 percent.
