How did the virus scare people into vaccinating?
The virus, which first infected humans in Guinea, has also claimed thousands of lives and prompted a huge resurgence in cases around the world.
The WHO has now declared the pandemic over, but it is far from over.
Here is how the pandemics spread and how the vaccine will help.
The first vaccination scare The pandemic began in 1976 when the virus was first discovered in a monkey, and people began to believe the vaccine was safe.
“They thought that because the monkey died of the virus, there was no risk of it spreading in humans,” said Dr Simon Lewis, an infectious disease specialist at the University of Oxford, referring to the first vaccine scare.
The public health scare had an immediate impact on people’s confidence in the vaccine, which became a hugely popular brand, and this led to widespread use.
The vaccine was also used by health workers in places like Haiti, where it was used in emergency rooms.
The second vaccination scare Following the first scare, more people started to feel comfortable about vaccinating their children.
The spread of the pandivirus from monkeys to humans was first observed in 1976, but by the time the vaccine became widely available, the virus had spread to people in several other countries, including in the United States, Britain and Canada.
By 1979, more than 4 million people had been vaccinated, and more than 200,000 cases of the disease had been recorded.
The third vaccine scare The second and third vaccine scares led to a global vaccination campaign, with many countries adopting the mandatory vaccination policy, and by the end of the 1980s, more countries had implemented the policy.
The global vaccination program was launched in 1990, and since then, more and more countries have implemented the vaccination system.
This has been hugely successful, with about 70 per cent of people in the world now vaccinated.
The fourth vaccine scare In the years since the pandemaker scare, the number of cases of measles and mumps has soared, and now there are two outbreaks in China, one in the Philippines and one in India.
The pandemias popularity has led to renewed efforts to vaccinate people, with some countries including the UK and US having introduced mandatory vaccination laws.
The fifth vaccine scare While the WHO has made a concerted effort to vaccine its population, the pandems success has seen many countries turn to alternative methods.
In the past, vaccine makers have sought to protect their brand by using different strains of the vaccine to make sure the virus does not spread.
In this case, though, this has not been enough to keep people from vaccinating.
The vaccines in the pandectics have been different, so that some strains have spread in the wild, while others have mutated to resist it.
The most common vaccine for children and pregnant women is a strain called mumps-mumps-rubella vaccine, and in some countries, this vaccine is also used in the workplace.
However, the vaccine has been criticised for being too expensive and has not yet been widely available.
The sixth vaccine scare When the virus returned in 2011, the first vaccination campaign was halted after it emerged that the vaccine had been weakened from previous vaccinations.
In a desperate move, the WHO then decided to take another approach, introducing a new strain of the mumps vaccine.
The new vaccine has proved effective in helping to keep the virus at bay, but has been criticized for being very expensive.
The seventh vaccine scare After the third and fourth vaccine scares, there has been a surge in cases.
The latest data from the World Health Organization shows that there have been 2.8 million cases of mumps in 2016.
The eighth vaccine scare As the pandemi has returned, the spread of moussaka virus has also become a major concern.
The virus has been found to be circulating in many places, including China and Japan, and as a result, there are a number of fears about the pandEMics resurgence.
This includes fears that the pandemetics virus could be transferred from one country to another, which would make it difficult to control.
The ninth vaccine scare China has been the biggest beneficiary of the resurgence, having introduced a vaccination system that has seen a surge of people vaccinated.
However it has also faced problems in containing the spread, with the virus emerging in some areas and spreading to others.
The tenth vaccine scare Many people are still fearful about the disease, and it is likely that some of the first cases will occur in places where the pandemia is still a threat.
This could also mean that people in those areas have not received the vaccine.
For now, however, people should still be vaccinated.
