Flu Vaccine, Then and Now - Last year many Americans, fearful of a new swine flu virus, clamored for vaccines that were often hard to find or even unavailable in their area. This year there should be plenty of vaccine for everyone who wants it.

The problems last year stemmed in large part from the late emergence of an unexpected strain — the swine flu — which was impervious to the standard flu vaccines then being prepared.

Manufacturers had to switch plans in midstream and start producing a second vaccine. They got a late start, many experienced production problems, and deliveries of swine flu vaccine ran way behind schedule.

People who sought the vaccine often found that their doctors had run out, or had to wait hours in line if they could find a clinic or a store with a supply.

Meanwhile, individuals who wanted complete protection had to get two flu shots, one to protect against the swine flu that was already circulating, the other against seasonal flu strains that were expected to circulate but never did appear to any significant extent.

This year immunization will be much simpler. The vaccine will protect against both the swine flu and two other flu strains. Most people will need only a single shot.
By mid-October, manufacturers had delivered 139 million doses and were projecting that they would produce 160 to 165 million doses in all for this flu season. That should be plenty to handle the likely demand.

Federal health officials now recommend that all people ages 6 months and older should get vaccinated. Influenza activity is relatively low around the country, but it makes sense to get protected soon, before the virus arrives in force.
