there's been a lot of bad PR against Vaccines lately
Anti-Vaxxers...you may have heard of them?
Perhaps the people who COULD have developed a new vaccine didn't want to endure it.
Perhaps they didn't want to be called monsters and accused of genocide?
Be careful what you want, you may get it.

Have you seen the documentary Vaxxed? If not, please do. There is so much corruption in this industry that leaves you scratching your head, like what you talked about in this post. Thank you for sharing.

If Cholera was vaccinated against it wouldn't be able to be used as a weapon as I believe it was in Haiti when it was introduced (accidentally of course ;-) by the UN or in Yemen where it is further devasting an already devastated population. 
You've pointed out something seemingly obvious & you have to wonder whether the decision was deliberate or alternatively come up with excuses as offered by @everittdmickey (which could of course be correct)

It all makes perfect sense  when you follow the money.

Africa & Southeast Asia don't have huge medical insurance industries and, therefore can't be pumped for cash like the developed countries.

Plus, Africa has vast natural resources that can be exploited once big segments of the population die off.

Hello @kafkanarchy84
These new vaccines have the potential to significantly reduce suffering and death from EV71 disease in China and in the future, the rest of the world. Nevertheless, manufacturing capacity and policy challenges remain for market entry and regulatory applications in other countries in the region with large populations of infants and children. Some questions remain: Will Chinese manufacturers make the vaccine available to other countries with EV71 outbreaks? Cross-protection of the vaccines against pandemic virus strains? How will they incorporate EV71 vaccine into the EPI? Can the vaccine be co-administered with other vaccines? How do you standardize the vaccine quality control and evaluation of EV71 vaccines? Having 2 vaccines against HFMD made in China is not only a milestone in the global vaccine field, but a testament to the hard work and innovation of the country’s scientific community and a boost to the local manufacturing sector.

I think that there are several factors in play, and the biggest is profitability.  If the demand will not be tremendous, the vaccine will not be developed or distributed.  It follows the same logic as 'orphaned diseases' - diseases that are not widespread enough to make research and development into possible cures unprofitable.  

In developed countries, many diseases are considered to have been wiped-out, and conditions unlikely to produce an outbreak, so mass-vaccinations are not being performed.  As global travel increases, we may have to rethink that strategy.

I am seriously wondering whether the whole anti-vax movement is orchestrated in order to re-awaken some of these diseases, and perform some sort of a mass population-cull.  I really don't understand why people would put their children at risk of some of these diseases, and if they simply cannot understand that the only reason they are not suffering from them right now is because everyone else took the vaccines and as a result there is herd-immunity.  Really sad, but their children will be the first to sicken and die when the epidemics hit, but it was, in the end, their choice.  Sadly, some of the people who were responsible and took the vaccines will die along with them, though.

👍

At a time when the government is sponsoring mass immigration you would think we'd see all the warnings and cautions that immigrants may be bringing in these diseases. But the government does not want to put it's own foot in mouth, and let us all know that there is a potential danger from mass immigration. It seems to be collusion. Because your points make complete sense, if the danger is at the same potential, why not? Just theorizing, but I bet once it is an established epidemic, that they allowed, we would be more than willing to be vaxxed in the panic. Might want to buy stock in Merck.

Hello, my name is Urma.

I currently take care of a young adult who was vaccine injured with Autism after receiving the Varicella vaccine. Today he has improved considerably, however, it is clear that the Autism is still preventing him from leading a normal life.

Please if you care about your child's health, don't get vaccinated
