"Prevnar, a vaccine that is dramatically decreasing the number of American babies' infections from a common but serious bacterium, also increases the number of other infections the babies get..."
Prevnar, a 7-valent pneumococcal conjugate vaccine marketed by Wyeth, helps prevent routine fevers, headaches, and earaches in young children—as well as rarer, invasive infections with bacterial pneumonia or meningitis—caused by the seven most widespread varieties of 90 types of pneumococcus bacteria. Kids and adults routinely carry all 90 strains in their noses and throats, even when they are not sick.
Prevnar is already becoming somewhat less effective against infections of the middle ear, according to the CDC's Cynthia Whitney. "It's a big headache for us… the numbers just aren't as good as one would like," she said.
Prevnar vaccination also enables a slight increase in middle ear infections caused by two unrelated bacteria. These infections spread more easily because the vaccine wipes out their seven former competitors.
With Prevnar, once it eliminates the seven selected strains, all the others proliferate inside babies' noses and throats, waiting for an opportunity to start an infection or to spread to someone else.
Researchers had hoped that targeting the seven most common strains would provide more protection against the other 83, he explained. But if a replacement vaccine is eventually necessary, Pelton suggests a different approach: If you target something that's in all pneumococci, then you won't have this problem, he said.''
Yep, just fix up the vaccine faux pas with another vaccine.
Here's a run down of the ever increasing required vaccines...
Before starting school, I was required to get around 9 doses total,
by 1984, the required amount of doses, 21
by 1995 that climbed to 32
1999, a grand total of 36, which included 3 doses of the now recalled Rotashield
And even w/those 3 doses being recalled, by 2001, the vaccine manufacturer had made up for the loss by getting 4 doses of their new vaccine added to the schedule...not only did they make up for the lost revenues from the Rotashield, they managed to add a fourth dose of their new vaccine! Replacement and then some...
2001 required doses, 37
2002 the number climbs to 38-40
2003, no changes yet, but don't hold your breath.
