Low solar activity and colder climates pose an increased pandemic influenza risk during this grand solar minimum. Highly pathogenic avian H7N9, H5N1, and other influenza-A strains have already killed more than 2,000 humans worldwide since 2003. Worryingly since 2013, a newly emerging highly pathogenic avian H7N9 influenza strain has killed over 1,600 Chinese people in a growing epidemic each year.

These increased pandemic influenza risks make it a priority to pre-immunize the world’s population against high-risk, potentially pandemic H7N9 and H5N1 influenza-A viruses. These two influenza-A strains are knocking loudly at our species’ door; they have killed between 25 percent and 50 percent of infected humans (the percentage may be even higher).[1],[2],[3],[4],[5] A highly lethal pandemic flu outbreak could kill between one and three percent of the world’s population. This was the mortality rate during the 1918–1919 Spanish flu pandemic.[6]
For all diseases that can be prevented by vaccination, it is both absolutely imperative and the norm to immunize people before a disease emerges.[7],[8],[9] However, under the existing paradigm of pandemic influenza immunization and supply, governments and WHO wait until a pandemic emerges before calling for the manufacture of a pandemic flu vaccine to immunize the population. Under this paradigm, sufficient quantities of vaccine cannot be manufactured quickly enough[10],[11] to protect the world’s population before the peak of a pandemic’s mortality is reached.[12]
Since the 2009 swine flu pandemic, vaccine technology advances offering immunological protection against ongoing viral mutation have made it possible to immunize people ahead of the outbreak of a pandemic (i.e., pre-pandemic immunization).[13] An upgraded flu vaccine technology would permit a broader immunity against emerging pandemic flu strain mutants, and enable us to better protect the population before the outbreak of a pandemic.[14],[15],[16],[17],[18],[19],[20],[21],[22] Why haven’t we upgraded the flu vaccine technology and implemented pre-pandemic immunization? You can read Chapter 14 of “Revolution: Ice Age Re-Entry” to find out more.
Developing nations produce a significant share of the world’s food. Look at the top five grain exporters in the following citation and you will see the importance of developing nations to grain supply and global food security.[23] Developing nations will be hit hardest by vaccine supply inequities, because their people will not be immunized in time under the current plan for supplying pandemic flu vaccine.[24],[25],[26] People living in developed nations will be hard pressed as well, unless their governments have stockpiled sufficient quantities of a pre-pandemic flu vaccine (unlikely).
There is clearly a need for change, what I term a pandemic flu vaccine revolution. With a pandemic flu vaccine revolution our governments could ensure we are protected, and our fragile global economy and the global food supply are insured against the increased pandemic influenza risk. Pre-pandemic immunization makes good sense before a climate switch and the increased pandemic flu risks it portends.
