That could account for the discrepancy. He was age-appropriately vaccinated, but not yet fully vaccinated. |
The first vaccine typically confers full immunity. The second vaccine is a "just in case" for the very small percentage that don't get full immunity from the first. So says the MMR vaccine info sheet I got last week. |
| my vacinnated 2 yo got chicken pox |
| No vaccine is 100% effective for 100% of the population. That is why it is important to keep vaccine rates high, so that those who do not have an effective response to the vaccine or those who cannot have vaccines are protected via herd immunity. |

So there's a strain of measles going around, that isn't covered by the current vaccine?
Has it mutated? |
chicken pox is only 85% effective - measles is a lot higher |
Someone has been watching waaaaaay too many movies. |
It's the same strain it always was, but no vaccine is 100% effective. There will always be people that get the virus despite the vaccine. |
| Does anyone know what the status of the two people are who caught it? I don't know how serious measles is - are the hospitalized? Is this life threatening? |
+10000 ESPECIALLY those who are high risk, who are infecting everyone else! |
Most children who get measles are just sick, occasionally enough to be hospitalized. However, there is a not insigificant risk of permanent damage such as deafness, impaired vision, and spasticity. Death is possible but permanent impairment is a greater risk. I don't know what happens to adults who get measles. Typically, childhood illnesses are much more severe when they occur in adults. The first victim in NOVA was a child who hospitalized several days. From the descriptor of places the second victim visited, there is a good chance he or she is an adult and, thus, may be sicker than the first victim was. |
