Is there a bird flu vaccine?
There is currently no vaccine available to the public.
The government does have a supply of a vaccine for one type of H5N1 bird flu virus and could distribute it if there was an outbreak that spread easily from person to person..
How did bird flu start?
Although there are several types of bird flu, H5N1 was the first avian influenza virus to infect humans. The first infection occurred in Hong Kong in 1997. The outbreak was linked to handling infected poultry. H5N1 occurs naturally in wild waterfowl, but it can spread easily to domestic poultry.
Where did the Spanish flu start?
While it’s unlikely that the “Spanish Flu” originated in Spain, scientists are still unsure of its source. France, China and Britain have all been suggested as the potential birthplace of the virus, as has the United States, where the first known case was reported at a military base in Kansas on March 11, 1918.
Is bird flu airborne?
Avian influenza viruses can be transmitted directly from wild birds to domestic poultry or indirectly e.g. through contaminated material. The virus spreads directly from bird to bird via airborne transmission or indirectly, through faecal contamination of footwear or feed.
How long did it take to get a vaccine for Ebola?
In response to the West African Ebola outbreak in 2014/15 the rVSV Ebola vaccine was put through all three phases of clinical development in just 12 months with focused coordination by the WHO, MSF (Doctors Without Borders) and the manufacturer.
How long did it take for a vaccine for h1n1?
“The most we’ve ever done for seasonal flu vaccine is about 120 million doses in 75 days,” he tells WebMD. “At this point, with an antigen-alone pandemic vaccine, we would see about 160 million doses in 30 days.
How long did bird flu last?
Globally, from January 2003 to 15 October 2020, there were 861 cases of human infection with avian influenza A(H5N1) virus reported from 17 countries. Of these 861 cases, 455 were fatal (CFR of 53%). The last case was reported from Nepal on 30 April 2019 (source).
Where did the swine flu start?
The swine-origin influenza A (H1N1) virus that appeared in 2009 and was first found in human beings in Mexico, is a reassortant with at least three parents. Six of the genes are closest in sequence to those of H1N2 ‘triple-reassortant’ influenza viruses isolated from pigs in North America around 1999-2000.
How long did it take to get a vaccine for bird flu?
Using laboratories in the WHO influenza network, and following procedures established by WHO to detect and respond to a new influenza virus subtype, a prototype virus could be made available to vaccine manufacturing companies within about four weeks.
What stopped the bird flu?
nothing happened. The virus continued to kill chickens and to occasionally infect and sometimes kill people. But as the years passed, the number of human H5N1 cases subsided. There has not been a single H5N1 human infection detected since February 2017.
Is bird flu still a threat?
While bird flu usually poses no threat to humans, instances of transmission of bird flu to humans have been reported since 1997, and over 100 people were infected in an outbreak that began in Southeast Asia in mid-2003.
What was last pandemic?
The 1918 influenza pandemic was the most severe pandemic in recent history. It was caused by an H1N1 virus with genes of avian origin. Although there is not universal consensus regarding where the virus originated, it spread worldwide during 1918-1919.
Can you vaccinate chickens against bird flu?
Birds are not vaccinated against flu in the UK and the available vaccines used in other countries are unable to protect against all strains of flu, so each strain requires a different vaccine.
How many cases of h1n1 occurred in 2009?
From April 12, 2009 to April 10, 2010, CDC estimated there were 60.8 million cases (range: 43.3-89.3 million), 274,304 hospitalizations (range: 195,086-402,719), and 12,469 deaths (range: 8868-18,306) in the United States due to the (H1N1)pdm09 virus.
