United StatesThe FDA Vaccines and Related Biological Products Advisory Committee (VRBPAC) recommended that the quadrivalent formulation of egg-based influenza vaccines for the US 2021-2022 influenza season contain the following:
an A/Victoria/2570/2019 (H1N1) pdm09-like virus;
an A/Cambodia/e0826360/2020 (H3N2)-like virus;
a B/Washington/02/2019- like virus (B/Victoria lineage);
a B/Phuket/3073/2013-like virus (B/Yamagata lineage).The committee recommended that the quadrivalent formulation of cell- or recombinant based influenza vaccines for the US 2021-2022 influenza season contain the following:
an A/Wisconsin/588/2019 (H1N1) pdm09-like virus;
an A/Cambodia/e0826360/2020 (H3N2)-like virus;
a B/Washington/02/2019- like virus (B/Victoria lineage);
a B/Phuket/3073/2013-like virus (B/Yamagata lineage).For trivalent influenza vaccines for use in the US for the 2021-2022 influenza season, depending on the manufacturing method of the vaccine, the committee recommended that the A(H1N1) pdm09, A(H3N2) and B/Washington/02/2019-like virus (B/Victoria lineage) viruses recommended above for the quadrivalent vaccines be used.
The Lewy bodies typical to PD are not seen in Mn-induced parkinsonism.Agent Orange may be a cause of parkinsonism, although evidence is inconclusive and further research is needed.Other toxins that have been associated with parkinsonism are:

Annonaceae
Carbon monoxide
Carbon disulfide
Cyanide
Ethanol
Hexane
Maneb/Mancozeb
Mercury
Methanol
MPTP
Paraquat
Rotenone
Toluene (inhalant abuse: "huffing")

Vascular
Binswangers disease (subcortical leukoencephalopathy)
Vascular dementia (multi-infarct)

Other
Chronic traumatic encephalopathy (boxers dementia or pugilistic encephalopathy)
Damage to the brain stem (especially dopaminergic nuclei of the substantia nigra),basal ganglia (especially globus pallidus) and the thalamus. Hypothyroidism
Orthostatic tremor
Paraneoplastic syndrome: neurological symptoms caused by antibodies associated with cancers
Rapid onset dystonia parkinsonism
Autosomal recessive juvenile parkinsonism

Society and culture
In the United States, the 2021 National Defense Authorization Act (NDAA) added parkinsonism to the list of presumptive conditions associated with Agent Orange exposure, enabling affected service members to receive Veterans Affairs disability benefits. References
