COMPLETE THIS FORM IF YOUR WORK INVOLVES GM VIRUSES AND/OR VIRAL VECTORS. ATTACH IT TO YOUR MAIN GM APPLICATION FORM

You will need to consult the “Compendium of Guidance from the Health and Safety Commission’s Advisory Committee on Genetic Modification, 1997”, Part 2B and its Annexes.

Part I:Risk assessment for human health and safety

1. Is the viral vector disabled? / Yes/No
2. Describe the origin of the virus, the mechanism of attenuation, and its stability in both the
parent viral vector and the recombinant vector
3. Indicate the probability of reversion to the wild-type
4. Is the viral vector replication competent? / Yes/No
5. Does the viral vector infect humans or human cells in vitro? / Yes/No
  1. Describe the nature of the inserted gene and the properties of the final genetically
modified viral vector
  1. Does the insert code for a protein with known or suspected physiological, pathological
and/or pharmacological effect? / Yes/No
  1. Is there reason to suspect that the tissue tropism or host range of the recombinant
virus will be any different from that of the parent vector or virus? / Yes/No
  1. Is there reason to suspect that the modified virus may have altered interactions with
host defence mechanisms? / Yes/No
10. If yes to Q9, will normal immune status be compromised by the modified virus? / Yes/No
11. Is vaccination available to protect against the modified virus? / Yes/No
  1. Is the recombinant likely to have an enhanced effect upon an immunocompromised
host beyond those normally expected with the parent host? / Yes/No
  1. Will viral susceptibility to anti-viral drugs (if available) be affected by the genetic
modification? / Yes/No
  1. Are all potential routes of transmission of the virus known, eg: those that may occur
during a laboratory accident? / Yes/No
  1. If yes to Q14, will the routes of transmission deliver the virus or its products to
tissues where it may be biologically active? / Yes/No
  1. Will the viral vector contain any natural or inserted oncogene and/or oncogenic
sequences? / Yes/No
17. Based on the responses given above, what level of containment is required for human safety?
Give reasons.

Part II:Risk assessment for environmental protection

  1. Are all potential routes of transmission or escape of the virus to the environment
known (e.g. following a laboratory accident)? / Yes/No
  1. Does the insert code for a protein with known or suspected inhibitory, detrimental,
or other physiologically active effect on any living organism? / Yes/No
  1. Is there reason to suspect that the tissue tropism of the recombinant virus in host
organisms will be different from that of the unmodified virus? / Yes/No
  1. Will the modified virus alter infectivity or interactions with host defence
mechanisms? / Yes/No
22. Will viral susceptibility to control agents be affected by genetic modification? / Yes/No
23. Will the insert cause changes in the host range of the virus? / Yes/No
  1. Is there reason to suspect that the modified virus may have enhanced environmental
survival factors; e.g. enhanced tolerance to UV, temperature, desiccation etc.? / Yes/No

Now complete the environmental Risk Assessment on page 3 of the main form. If you answered "yes" to any of Questions 19 to 24, give details on a separate sheet.

Inform your local Biological Safety Officer of any new developments with viral vectors you may have used. These will be reported to the Local GM Safety Committee and the University Biological Safety Officer.
