antigenic shift. That shift produces a new subtype that is different from the two parent viruses. When the new subtype contains genes from the human virus,a pandemic resulted because there was no immunity to the virus and no vaccine to protect against it.
I was really interested when I read this question as I had been researching this myself. The main pandemics in history have included:• Plague of Justinian, around 100 million died in Europe between 541 to 542• Black Death, between 50 to 200 million died of this between 1331 to 1353The recent COVID-19 Coronavirus has me concentrating on more recent pandemics, I wondered how does this compare? I found this infographic very useful for modern pandemics, this states that the pandemics of the last century were:• Spanish flu – which killed 17 million around 1918 to 1920• Asian flu – which killed 1.1 million around 1956 to 1958• Hong Kong flu – this killed around 1 million between 1968 to 1969• HIV / AIDS – this has killed 32 million people so far• Swine flu – this killed around 575,000 people between 2009 to 2010
Since the late 19th century, there have been several major influenza pandemics, including the 1918 H1N1 pandemic, also known as the Spanish flu, which resulted in millions of deaths worldwide. The Asian flu pandemic in 1957, caused by H2N2, led to significant mortality, particularly among the elderly. The Hong Kong flu in 1968, caused by H3N2, also resulted in substantial fatalities. More recently, the H1N1 pandemic in 2009, often referred to as the swine flu, emerged and spread globally, though it generally had a lower mortality rate than earlier pandemics.

Just about anyone who gets the flu. Most of the influenza viruses that cause disease in humans are Type A influenza viruses (but not all). Type A flu viruses are also what cause pandemics in humans.
Pandemic Flu Pandemic refers to contagious or infectious diseases that are usually worldwide or spread across several continents. Some examples of diseases that have caused past pandemics would be cholera, small pox, the bubonic plague, typhus, the Spanish flu, and the Asian flu. Flu refers to influenza. Human influenza pandemics, such as the 2009 novel swine flu (A-H1N1/09) pandemic, are caused by the influenza virus subtypes of A-H1N1. A-H1N1/09 is the subtype that caused this recent swine flu pandemic. It was declared a pandemic on June 11, 2009 by WHO (World Health Organisation).

"Cow flu" seems to me more of a satirical sense of "illness" that is only made up by those who like to BS, after the pandemics of swine flu and bird flu that had passed around in previous years. In a more serious sense, cow flu doesn't exist. So I wouldn't worry about it.
That refers to Type A influenza viruses that are common with our seasonal flu. There are two flu types that humans get: Type A and Type B. The flu vaccine contains some of both types to prevent infections from them. All of the flu pandemics we have had over history have been caused by Type A flu viruses, they are typically very easily transmitted from person to person. Don't forget to get a flu shot ASAP now that it is October - the start of the Northern Hemisphere flu season.

Scientists today are using genetic data from the Spanish flu virus to better understand viral evolution, transmission, and immune responses. They have discovered that the Spanish flu's genetic makeup can provide insights into how influenza viruses adapt and cause pandemics, which is crucial for developing vaccines and treatments. Additionally, research on the immune response to the Spanish flu has informed current strategies for dealing with respiratory viruses, including COVID-19. This historical data helps improve preparedness for future pandemics by identifying patterns in viral behavior and human responses.
The 1918 flu pandemic and the H1N1 pandemic of 2009 both involved strains of the influenza virus and spread rapidly across the globe, causing widespread illness and death. Both pandemics disproportionately affected younger, healthier populations, contrary to typical flu patterns that primarily impact the elderly. Additionally, both pandemics prompted significant public health responses, including vaccination efforts and social distancing measures, highlighting the importance of preparedness for infectious disease outbreaks.
