Smallpox immunity from childhood jabs has died out, says study
---------------------------------------------
Only a tiny fraction of people who were vaccinated against smallpox
before the disease was declared eradicated more than 2 decades ago
have still retained their immunity, according to a U.S. study. The
figures are bad news to those who believe that they will be protected
against a smallpox bioterror weapon thanks to a jab in their
childhood.
Of 621 microbiologists in Maryland who received fresh vaccinations
against smallpox between 1994 and 2001 to protect them in their daily
work of handling dangerous viruses, only 6 percent were still immune
from their early vaccination.
The U.S. government is planning to buy 286 million of doses of
smallpox vaccine by the year (sic), enough to protect every American
from the disease. However, health professionals are divided as to
whether it is best to vaccinate everyone immediately, in a
pre-emptive campaign, or wait until there is any clear threat. A
pre-emptive campaign would make it far easier to contain any outbreak.
However, many people would die -- at least 180 in the US population
-- because of health complications arising from the vaccine, says the
British weekly New Scientist, which reports on the Maryland research
in next Saturday's issue.
Smallpox was declared eradicated by the World Health Organization in
1980, prompting countries around the world to stop routine
vaccinations. The virus is highly transmissible from person to person
and has a 33 percent mortality rate.

As Experts Debate Need for Voluntary Smallpox Vaccination, 3 in 5 Say
They Want It
--------------------------
Although not a single case of smallpox has been reported in the
United States, 3 in 5 Americans (59 percent) surveyed by the Harvard
School of Public Health and Robert Wood Johnson Foundation say they
would get vaccinated as a precaution against a bioterrorist attack
using smallpox if a vaccine were made available to them.
This is the case even though people were told that the vaccination
may produce serious side effects in a small number of cases. If cases
of smallpox were reported in their own community, more than 3/4 (81
percent) of Americans say they would get vaccinated. This includes
the 59 percent who had already said they wanted to get vaccinated in
the near future, even without cases having been reported, as well as
an additional 22 percent who became interested in vaccination once
local cases were mentioned. One in 10 (9 percent) would not get
vaccinated even if an outbreak of smallpox occurred in their
community.
These findings, based on interviews with 2000 Americans nationwide,
come at a time when 2 federal government advisory committees of
experts, the Advisory Committee on Immunization Practices and the
National Vaccine Advisory Committee, are debating whether or not
voluntary smallpox vaccinations should be offered to the public.
Also starting on Thu 6 Jun 2002, in New York City and San Francisco,
the Centers for Disease Control and Prevention is conducting a series
of public forums on the use of the smallpox vaccine.

"The survey results also raise the question of whether or not the
country should move ahead with voluntary vaccination of frontline
workers, such as doctors, nurses, and emergency personnel," said
Robert J. Blendon, professor of Health Policy and Political Analysis
at the Harvard School of Public Health. "If there were a bioterrorist
attack using smallpox, millions of Americans would want to find
health professionals to vaccinate them. If the professionals
themselves have not been vaccinated, it could lead to serious delays
and public panic."
The substantial public interest today in receiving a smallpox
vaccination grows in part from continuing fears about a future
bioterrorist attack. Now, 9 months after the September 11th attacks,
more than 4 in 10 (43 percent) report being worried about a future
attack using smallpox, down from 53 percent in November 2001. About
half (49 percent) of women, compared with 36 percent of men, are
currently worried about such an attack.
The interest in vaccination may also reflect Americans' familiarity
with the smallpox vaccine. Nearly 3 in 5 Americans (56 percent)
report having been vaccinated earlier in their lives. In the near
run, the public sees little risk that they or a family member will
get smallpox. Only 1 in 12 Americans (8 percent) believes that they
or someone in their immediate family is likely to contract smallpox
during the next 12 months. This compares with [1 in 5] 20 percent who
believe they or a family member are likely to be injured in some
other type of terrorist attack.
Most Americans (74 percent) are at least mildly optimistic that they
would survive if they contracted smallpox and received immediate
medical care, 44 percent see it as very likely that they would
survive, while 30 percent thought it somewhat likely.
The public is also somewhat optimistic that adequate planning,
preparation, and professional education have taken place in their
community in regards to a possible smallpox attack. Most Americans
(84 percent) report confidence that their own doctor can recognize
the symptoms of smallpox. Almost half (45 percent) are very
confident. [Really! - Mod.JW]
About 2/3 of Americans (70 percent) believe that their local hospital
emergency room is prepared to diagnose and treat people who have
smallpox. However, this includes only 23 percent who think their
local ER is very prepared. Similarly, 2/3 (66 percent) are confident
that their local health department is prepared to prevent smallpox
from spreading if there were an outbreak of the disease, but this
includes only 19 percent who think the local health department is
very prepared. If they had symptoms of what they thought might be
smallpox, most Americans would seek help from the traditional health
care system. The most common place to turn for diagnosis or treatment
would be their own doctor or medical clinic (83 percent), followed by
a hospital emergency room (62 percent) or outpatient department (52
percent). Very few Americans (27 percent) would seek assistance from
a public health department clinic.
The survey finds that there is no single spokesperson the public most
trusts on these issues. When asked, in the event of an outbreak of
disease caused by bioterrorism, which of 6 public officials they
trusted most to provide correct information about how to protect
themselves and their families from the disease, 43 percent said a
senior scientist from the Centers for Disease Control.
No other official was chosen by more than 16 percent. The other
choices were the heads of the Department of Health and Human
Services, Office of Homeland Security, and FBI, the U.S. Surgeon
General, and the city or state health commissioner. Asked whom they
trusted most to provide correct information about where to go if they
were exposed to a disease caused by bioterrorism, Americans were
nearly evenly split between the CDC (28 percent) and their city or
state health commissioner (26 percent); 19 percent chose the head of
the Department of Health and Human Services.
Americans' knowledge about smallpox is mixed. More than 3/4 (85
percent) know that smallpox is contagious. Many believe that smallpox
is easily spread. For instance, 90 percent know that if someone has
contracted smallpox and has the symptoms, they should be kept
isolated from uninfected people.
However, less than half (43 percent) of Americans know that if a
person has been exposed to smallpox but does not have symptoms,
getting a vaccination would prevent the person from coming down with
the disease. Only about 1/3 (32 percent) know that once a person
develops symptoms of smallpox, there is no cure. "This is the central
issue for public health education," said Blendon. "Americans need to
know that according to experts, if people are exposed to smallpox but
do not yet have symptoms, an immediate vaccination will help protect
them against the disease. The message is that you should not wait
until you get sick. If you have been exposed, go get vaccinated right
away, because once the symptoms start, there is no treatment to stop
the course of the disease."
Since the Fall of 2001 there have been only a few changes in
Americans' behavior in response to bioterrorist threats. Most
Americans continue to believe that in the near run they or someone in
their immediate family is unlikely to contract anthrax or smallpox.
Currently, 10 percent think they or a family member is likely to
contract anthrax during the next 12 months, down slightly from 14
percent in October 2001 shortly after anthrax-laden mail was first
discovered, but nearly identical to the 9 percent figure in
November-December 2001.
The proportion of Americans believing that they or a family member is
likely to contract smallpox during the next year has remained
virtually unchanged: 9 percent in October 2001, 8 percent in
November-December 2001, and 8 percent currently.
Decreases have been seen in the proportion of Americans who:
- are taking mail precautions (from 37 percent in October 2001 to 24
percent in May 2002)
- are avoiding public places and consulting a website for information
about how to protect themselves in case of bioterrorism (from 12
percent each in October 2001 to 7 percent and 8 percent,
respectively, in May 2002).
Of note, there has been a significant rise, from 5 percent in October
2001 to 15 percent in May 2002, in the proportion of Americans who
report that they or someone in their family has gotten a prescription
for or purchased antibiotics in response to concern about
bioterrorism. This suggests that some Americans are stockpiling
antibiotics in case of a future bioterrorist attack.
