Why Pertussis is Making a Comeback

http://well.blogs.nytimes.com/2016/02/22/why-pertussis-is-making-a-comeback/?ref=health&_r=0

Notes/

_ In recent years, there have been several outbreaks reaching numbers not seen since the 1950s.

_ A recent study from California confirms what earlier reports have suggested: that the newer pertussis vaccine, reformulated to be safer and have fewer side effects than the older version, just isn’t as effective.

_ The new vaccine provides reasonable short-term protection during the first year, but the protection wanes over the next few years

_ “The levels at which it’s occurring now haven’t been seen in at least 50 years,” Dr. Klein said.

Summary /

In recent years, there have been several outbreaks reaching numbers not seen since the 1950s.“The biggest driver is waning immunity from our vaccines,” said Tami Skoff, an epidemiologist with the division of bacterial diseases of the C.D.C. “The protection doesn’t last as long as we originally thought it would.”

Pertussis had never been eradicated. Having the disease does not confer lifelong immunity. But the last time there were more than 40,000 infections in the United States was in 1959. That was down from a high of more than 265,000 infections in 1934. By 1976.

School IT system freezes

Notes/

- schools have reported a number of problems with the system .

- the program was scheduled to be operating in schools by  2018.

- LMBR delayed the group of 229 .

Summary /

The education department has confirmed the learning Management and Businessmen Reform (LMBR) is still only in place in 229 pilot schools across the state .

Rollout of state's  disastrous new program stalls amid concerns by TAFE .

A departmental memo late last year revealed plans for the LMBR to be deployed in more schools from may . But that scheduled could be pushed back .    
Personal Reflection /
i think that the state government should test the new IT program before rolllout it because its going to effect the TAFE and schools students which could causes the IT system freezes . And the state government should scheduled the right tome to rollout the program to avoid any delays which could effect the students .  

From 1992 to 2002 , immigration to Australia has changed , as we see in these charts , the immigration from some countries decreased . For example, in dome regions like Europe and USSR , the immigration from there decrease dramatically , on the other hand , we see some regions like some African countries increase rapidly because of the situation there.
